As leading industrial flooring contractors based in Worcestershire, at PSC Flooring we ensure that the preparation of the the flooring is done to the highest standards. Moreover, preparation of the existing industrial floor surface is the key to a perfect resin flooring system finish.
Industrial Floor Preparation
Depending on the size of the area, the preparation can be done in two main ways: –
Diamond Grinding
We typically use the diamond grinding process for smaller areas. The process involves using a specialised diamond grinding machine with rotating grinding blades with diamond tips to remove a thin layer from the surface of the concrete floor. Then, we push the machine along manually, and the depth of the surface removed is determined by the height; a diamond grinder can remove as much or as little of the substrate surface as needed. Also, for small or intricate areas, we will often use a handheld diamond grinder.
What power supply does a totally enclosed diamond grinding machine require?
A totally enclosed diamond grinding machine requires a 3 phase, 415 volt power supplied via 32 amp socket.
Shot Blasting
Larger areas typically require shot blasting. Shot blasting rapidly impacts the base concrete/substrate surface with a controlled stream of abrasive shot material. Similar to sandblasting, which is mainly used for metallic surfaces, shot blasting utilises a turbine to accelerate the abrasive shot.
Furthermore, the rate of the turbine and the speed at which the machine moves across the floor determine the hardness of the blast. Therefore, faster rates result in a harder impact on the concrete. The machine collects the abrasive shot after it hits the floor and then reapplies it.
Wick Care Farm – Commercial Flooring
Wick Care Farm, a farm-based wellbeing establishment in Wick, Pershore, recently called PSC to assess a 105 square metre floor area.
During the site visit, we discussed the requirements for the Activity Room, Kitchen Area, and toilets, totaling 105 square metres. The client wanted a hardwearing and easy-to-clean floor surface. Therefore, PSC recommended laying a nominal 6mm RT polyurethane screed with one coat of DD polyurethane coating system in silk.

Preparation of Floor Surface
We prepared the entire floor area by thoroughly cleaning the existing concrete floor surface using the totally enclosed diamond grinding machine. Moreover, we then vacuumed all residues and dust with a 110v triple motor vacuum. Additionally, we made 6mm x 6mm saw cuts to the perimeter of the floor area, door thresholds, around drains and gullies, and where necessary to toe in and anchor the screed. Finally, the floor was then ready to receive the nominal 6mm RT polyurethane screed.
105 Square Metres Nominal 6mm RT Polyurethane Screed
We applied a coat of epoxy resin primer incorporating a heavy scatter of 0.7 x 1.2mm quartz aggregate to the entire area. Then, we hand trowelled the nominal 6mm RT Polyurethane resin screed system onto the 105 square metres in the client’s chosen Resedv Pumadur RT polyurethane, textured, matt, Mid Grey. We finished with one coat of Pumadur DD polyurethane seal coat, in clear, silk.
The work was completed in just 2 days – on time and within budget.
“We were very impressed with the whole job from PSC Flooring. We wouldn’t hesitate to recommend them to others.”
